PUDDLING MECHANISM.

SPECIFICATION forming part of Letters Patent N 0. 665,876, dated January15, 1901. Application filed November 9, 1899. Serial No. 736,881. \Nomodel.)

To all whom, it may concern:

Be it known that I, ROBERT A. CARTER, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Puddling Mechanism, of which improvements the followingis a specification.

The invention described herein relates to certain improvements inmechanism for puddling iron, and has for its object the employment of amotor for reciprocating the puddling bar or hood, the motor being somounted as to permit of its being shifted vertically and horizontally,thereby rendering it possible to reach all portions of the metal withthe bar or hook.

The invention is hereinafter more fully de scribed. and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is an end elevation of a puddling-furnace having myimprovements applied thereto. Fig. 2 is a sectional elevation of thepuddling mechanism. Fig. 3 is an underside plan of the powercylinder.Fig. -i is a sectional plan view, and Fig. 5 is a transverse section ona plane passing through the valve mechanism.

In the practice of my invention the motor (the fluid-pressure cylinder1, with its piston 2, being a desirable form thereof) is supported by arod 3, which has its inner end attached to a part of thepuddling-furnace A, preferably to the sliding door 4c, as shown inFig. 1. The outer end of the rod 3 is movably supported by acounterweight 25, connected to the rod by a rope 26, passing over thepulleys 27, which are supported in any suitable manner. In order topermit of the shifting of the motor both vertically and horizontally,the inner end of the rod 3 is connected to its support by a universaljoint of any suitable construction, the ball-and-socket joint 5 being aconvenient form thereof. In order to permit of the shifting of themotorindependently of the supporting rod or rail, it is connectedthereto by a universal joint, preferably of the ball-and-socket type, asshown at 6. One

part of the universal joint 6 is formed on or secured to a sleeve 7,adjustably mounted on the rail or rod 3, thereby permitting of theadjustment of the motor toward or from the furnace. In order to preventinjury to the bottom of the furnace or a part of the puddling mechanismin case the point of the peddling bar or hook should catch, the motor isyieldingly held as against movement after it has been adjusted by meansof springs 8, interposed between the ends of the sleeve 7 and collars 9,adjustably secured on the rod or rail 3. This construction permits ofthe adjustment of the motor and also provides cushions, which willprevent injury to the furnace or puddling mechanism.

While any form or construction of motor whereby to effect a uniform ormanually-variable reciprocation of the puddling-tool may be used, it ispreferred to employ a fluid-pressure cylinder 1 for that purpose. Thiscylinder has one part or member of the universal joint 6 formed on orsecured thereto. Fluid, preferably air under pressure, is conducted tothe valve-chamber of the cylinder by a flexible pipe 10, as shown inFig. l. The flow of fluid to and from the ends of the cylinder iscontrolled by any suitable form or construction of valve-such, forexample, as that shown. Thisvalve consists of a rotary plug 11, providedwith suitable ports or passages, whereby the passages 12, leading to theends of the cylinder, may be connected alternately to the inletport 13and exhaust-port 14. The regular shifting of this valve may be offectedby any suitable construction of mechanism operated or controlled by thepiston or its connections. A convenient construction and arrangement ofsuch mechanism consists of pins 15, passing the heads of the cylinderand adapted to be shifted by the piston. Levers 16 are so mounted onbrackets 17 that their inner ends can be shifted by the pins 15. Theouterends of the levers are connected by a rod 18, provided with pins 19or other devices adapted to engage and shift the handle 20 on the valve11. This mechanism will effect the regular shifting of the valve 11; butit is at times desirable to vary the strokes of the piston, and in suchcases the valve 11 is shifted by the operator, the valve being releasedfrom its operating mechanism. In order to permit this release, the pins19 are carried by a sleeve 21, rotatably mounted on the rod 18 betweenthe collars 21 on said rod, and is held from rotation by a. set-screw 22or other suitable means. By turning back the set-screw the sleeve may beturned so that the pins 19 will not strike the handle 20, therebypermitting the valve to be shifted by the operator at will.

The puddling-tool 23 is detachably connected to the piston-rod in anysuitable manner-as, for example, by a socket 24 on the mit of suchmovements of the motor that the inner end of the puddling-tool willreach all portions of the bath. By mounting the in ner end of thesupporting-rod 8 on the door of the fnrnace'the rod can be raised out ofthe way of the workman in charging and drawing the furnace. As the outerend of the rod 3 is supported by the counterweight 25, the

shifting of the rod and the motor carried thereby can be easilyeffected.

I claim herein as my invention- 1. In a puddling mechanism thecombination of a furnace having a charging-door, a pivotally-mountedmotor-support arranged in suitable proximity to the charging-door andextending forward from the furnace and a motor carried by the supportfor reciproeating the puddling-tool, substantially as set forth.

2. In a puddling mechanism, the combination of the door of apuddling-fnrnace, a motor-support pivotally connected to the door and amotor for reciprocating the puddlingtool carried by said support,substantially as set forth.

3. In a puddling mechanism, the combination of a supporting-rod havingauniversallymovable connection to a suitable support, and a motor forreciprocating the puddlingtool having a universallymovable connection tosaid rod, substantially as set forth.

4. In a ,puddling mechanism, the combination of a supporting-rod havinganniversallymovable connection to a suitable support, a motor carried bysaid rod for reciprocating the puddling-tool and means for varying thestroke of the motor at the will of the operator, substantially as setforth.

5. In a puddling mechanism, the combination of a motor-support pivotallyconnected to the furnace, a motor carried by said support, apuddling-tool operatively connected to the motor and cushions interposedbetween the puddling-tool and the motor-support, substantially as setforth.

6. In a puddling mechanism, the combination ofa supporting-rod,pivotally connected to the furnace, a sleeve movable along said rod,cushioning-springs arranged at the ends of the sleeve and a motor forreciprocating the puddling-tool having a universally-movable connectionto the sleeve, substantially as set forth.

In testimony whereof I have hereunto set my hand.
